Please help me with homework

2-14:

A) 3x+5y=3(3)+5(2)

=9+10

=19

B) x²+y²=3²+2²

=9+4

=13

C) -5x+9=-5(3)+9

=-15+9

=-6

D) xy-1=(2×3)-1

=6-1

=5

E) 2x²-y=2(3)²-2

=18-2

=16

F) 2y-x+5+x²-3y=2(2)-3+5+3²-3(2)

=4-3+5+9-6

=9

2-15: area=y²+xy+xy

=(y²+2xy) un²

perimeter=y+y+y++y+x+y/2+y+x+y/2

=(6y+2x) un
